VENTILATING AIND nnrtncrrnsor n13 THROUGH BAILWAYCARS.

Application filed June 14, 1926, Serial No. 115,843, and in CanadaMay28, 1926. I

Hereto fore it has not been possible to obtain proper ventilation inrailway cars and particularly in so called reirigerator express cars forcarrying perishables because the air fectively difiused throughout thecar. The

' object of myinvention is to diffuse tresh'air' upwardly throughout theinterior of the car from the floor.

To. this end my invention consists in pro-' viding railway cars and moreparticularly cars for carrying perishableswith a ventilator whereby airis induced into the top of the car bythe forward movement thereof andpractically theentire body of air taken in is precipitated downwardlynear the forward end of the car and deflected into a flat airdistributing member extending substantially parallel and comparatively.close to the floor communicatesapair. of intercommunicating oppositelycurved deflectors, inside the car communicating wlth oneof the airintakes and disposed one below the other close to a side of the car. Thetop of the upper deflector projects within the ventilator and has itsconcave side towards that end-of thecar; and the lower deflector. restsin the corner of the car beneath the ventilator with its con cave sidetowards the body of the car and the upper and lower deflectors beingarranged, as shown in Figure 2 with the upper in position todirect thedownwardly-deflected air into the curve of the lower deflector. Thelower deflector projects the air into an air distributor in the form ofa floor rack which extends from'sideto side of the car and, the

air being thus deflected from the bottom ends of the lower deflectors,at that end of the car, to the bottom. ends, of the deflectors at theopposite end of the car. IInforder to control the volume of air admittedthe upper deflectors are preferably carried by sliding plates serving asvalves controlling the air intakes. Thesevalvular plates may be adjustedto vary .the intake opening or cut it off entirely. Each end of the carhas a screened theupper portion of opening preferably located inthelower portion of each of the doors otthe car and each is furnished withmeans for adjusting, or ii desired completely closing these screenedopenings. The mouths of the air intakes are adapted to exclude dust fromthe airadmitted by'vertically disposed fine screens; extendingcompletely across the same.

-An equipment in accordance with the foregoing causes pure airtopermeate the entire interior of a car and while it rises through thebody of the car near the front endwhere it is admitted nevertheless itwill be drawn down again as it nears the outlets in therear end of thecar by the position of the outlets near the floor.

For full comprehension, however, of my invention reference must be hadto the accompanying drawings in which similar reference charactersindicate the same parts and wherein; v 7 A v Figure l-is an end View ofa railway car constructedwith my means for ventilating and deflectingthemair admitted thereto, through the bodyof the car, this viewindieating one halt ofthe near end of the car in elevation and the otherhalf of the opposite end of the car in elevation, the body oi thecarwithin the last mentioned half as illustrated, being in transversesectional View;

Openings 4 are cut throughthe main deck 2and extend in width from. upper.deck 3 to a point-pin line with the upper end of the side. wall of thecar as shown in vliigure .1. Eachlof "these openings has a ventilatort Afitted therein and consistingtof a hood pre. senting a fiat top 5 withinwardly inclined back 6, Figure 2; the mouth of the ventilator having ascreen 7 extending across it. The

screened mouth of the ventilator is located at one end of the openin 4.A pair of oppositely curved deflectors and C are arranged one above theother, the upper end of the top deflector projecting within theventilator, and

is arranged with its concave side towards the end of the car while thelower deflector C rests in the corner of the car beneath the ventilatorwith its concave side towards the body of the car and in communicationwith the concave side upper deflector. Both deflectors are preferablyarranged in close proximity to a side of the car and the lower deflectoris preferably of slightly greater width than the upper deflector tofacilitate the distribution of the air deflected thereto by the upperdeflector. The openings 4 are closed by sliding valvular plates G uponone end of each of which is rigidly carried one of the upper deflectorsB so that by moving the sliding plates the ventilators may be partiallyor fully closed or opened. When the ventilator is closed in this mannerthe upper deflectors being carried by the plates will be placed incontact with the end of the car and out of the way.

The air entering through the ventilators at the forward end of a movingcar is deflected by the deflectors B and C and projected into a flat airdistributing member consisting of a floor rack D. This rack consists ofa false flooring composed of narrow spaced boards 8 supported at theiropposite ends on cross pieces 9 resting on posts 10. The spaces betweenthese boards serve as slits through which air may pass This form offloor rack admits the air projected along the floor by thelower'deflectors and the air thus admitted is distributed throughout thecar through the slits. In each end of the car the usual door 12 has itslower panel removed and the opening thus formed is covered by wire clothE. This screened opening is controlled by a valvular panel 14 slidablevertically in guides 15. \Vhen the car is put in motion the opening inthe door at theforward end of the car is preferably closed and theopening in the rear door is regulated by its valvular panel in relationto the adjustment of the valvular plate G controlling the air intake atthe forward end of the car. i

The device functions in either'direction as follows:

The speed of the car forces a current of air through the forwardventilators A in the roof and into the car where it is diverted by thedeflectors B towards the forward end of the car and onto deflector C.Deflectors C, because of their greater width, spread out the air bodyand direct it into the space under the floor rack by which it isdistributed throughout the car from which it is exhausted through therear ventilators A and end opening E.

It is claimed that this system of air intake and the arrangement ofdeflectors, coacting with the exhaust ventilators and end exhaust ingsare closed.

V11 at I do claim as my invention and which I regard as new and in whichI claim an exclusive property and privilege and which I desire to secureby Letters Patent are 1. In a railway car of the type described thecombination with an intake ventilator; of a pair of deflectors of curvedform and located one above the other, the upper deflector being disposedwith its concave side communicatin with the air intake, and the lowerdeflector being disposed with its concave side in communication with theupper deflector; a floor rack having the lower deflector communicatingtherewith, and an air outlet in the opposite end of the car.

2. In a railway car such as claimed in claim 1 wherein the intakeventilator communicates with anop'eningin the roof of the car; aslidefor controlling the roof opening and having the upper deflectorcarried thereby.

3. In a railway car the combination with a roof ventilator and avalvular plate for controlling the communication between the roofventilator and the car; of means for directing the air from theventilator towards the floor at the intake end of the car consisting ofa pair of substantially vertically aligned curved deflectors, one beingin communication with the roof ventilator with its concave side facingthe end of the car, and the other deflector resting in the corner of thecar beneath the roof ventilator with its concave side towards the bodyof the car, and in communication with the concave side of the upperdeflector, and means extending parallel to the floor of the car fordistributing the air throughout the car, and a screened opening withmeans for controlling the same in the rear end of the car.-

4. A railway car such as claimed in claim 3 and having the upperdeflector carried by the valvular plate controlling the passage throughthe roof ventilator.

In testimony whereof I have signed my name to this specification.
